The scheme usually involves accomplices, such as an interpreter and a taxi driver, all of which must be paid by the victim at an inflated price.
Everything is pre-arranged so that the wealthy foreigner pays high amounts of money for accommodation, is taken not to an ordinary public café but to the most costly restaurant (usually some out-of-the-way place priced far above what locals would ever be willing to pay), and is manipulated into making various expensive purchases, including gifts such as electronics and fur coats. The victim leaves just as alone but poorer at the end of the trip.
Letters are exchanged between the scammer and victim until the scammer feels they have groomed the victim enough to ask for money.
This might be for requests for gas money or bus and airplane tickets to travel to visit the victim, medical expenses, education expenses etc.
The young woman will contact a victim and tell them of their plight of not being able to remove the gold from their country due to being unable to pay the duty or marriage taxes.
The woman will be unable to inherit the fortune until she gets married, the marriage being a prequiste of the father, uncle or grandfather's will.
This was the finding of a study by Dr Martin Graff of the University of South Wales presented on Tuesday 26 April 2016, at the British Psychological Society Annual Conference in Nottingham, England.
Upon finding victims, scammers lure them to more private means of communication, (such as providing an e-mail address) to allow for fraud to occur.
The fraud typically involves the scammer acting as if they've quickly fallen for the victim so that when they have the opportunity to ask for money, the victim at that time has become too emotionally involved, and will have deep feelings of guilt if they decline the request for money from the scammer.
Scammers are very adept at knowing how to "play" their victims - sending love poems, sex games in emails, building up a "loving relationship" with many promises of "one day we will be married".
Often photos of unknown African actresses will be used to lure the victim into believing they are talking to that person.
